Watts spelled out some of the steps that Fast 5 Xpress took to limit the noise coming from the car wash, which has residential development to the south and east, and across the intersection of Murrieta Hot Springs and Jackson to the northwest.

Among those steps were setting the dryers 30 feet from the entrance to the 150-foot-long conveyor-style washing tunnel and putting noise reducers on the vacuum pumps, which will be inside the structure.

According to a report prepared for the commission, a six-foot block wall will be constructed at the nearest residential property line.

The facility also will have 20 parking spaces with vacuums so customers can clean the inside of the car.

Three different wash options will be available at $6, $9 and $12. Utman said the longer the car wash, the better, and more expensive, it will be.

He also said that the operation will have the latest technology, including $750,000 of computerized equipment and brushes composed of microfiber technology that does not scratch and will not collect sand and dust.

"We started researching this about three years ago," Utman said.

The company is planning to open several car washes in Southern California, with the first, in Irvine, scheduled to have opened over the weekend.

"You have not seen this in the city," Utman said.

Utman expects the car wash to service an average of 350 cars per day, and more on weekends.

Fast 5 Xpress conducted a neighborhood meeting on Aug. 20, 2012, but no one attended other than the applicant and broker, the staff report said.

Nobody spoke during the public comment portion of Wednesday's meeting.

The planning commission approved the project with a 4-0 vote. Commissioner Gregory Goodman did not attend the meeting.
